Now available from Industrial Test Systems, Inc. is a quick, easy, field test kit that can confirm the presence of inorganic arsenic in wood. Arsenic Quick™ 481396-W kit is a modification of the US Patented, ETV Verified arsenic test for drinking water. This 10 minute test readily confirms the absence or presence of arsenic in any wood sample, including CCA treated lumber using safe ...

Coliforms are the most widely accepted bacterial indicator of fecal pollution in water. Several commercially available portable kits make it possible to carry out on-site water quality testing, but are usually costly and often require technical expertise to operate. In developing countries like India, presence/absence test kits like the H2S test kits are commonly used for routine ...

Q: I already have a Checkit Test kit and now I want to expand it to measure another parameter – what’s the best way to do this? A: The Lovibond Checkit Test kits can easily be expanded to cover new parameters with a Testpak Testpak add-on packs let you test a new parameter without purchasing a whole new kit – ...

Comet-ME is an Israeli-Palestinian NGO providing sustainable off-grid energy and water services to rural Palestinian communities in the South Mount Hebron region of the occupied Palestinian territories. The local Palestinian communities are not connected to the water grid and people ...

The costs of hiring someone to test your breathing air lines on site can quickly add up, have you ever considered doing your own tests? The use of breathing masks and compressed breathing air is a vital component of maintaining safety standards on site. The air produced protects workers in spray booths, car body shops and other applications where isocyanate paint mixtures are ...

Methods for measuring toxicity or respiratory activity of microbial cultures can be used as tools for assessing the presence of chemicals and their impact on the streams. The proposed toxicity test is based on the respirometric characteristics of the bacteria according to the principals of Biolog’s microplate system. As the microorganism ...

The ability to rapidly monitor the quality of U.S. source water for contamination has never been more important than it is in today’s security-sensitive environment. The Delaware Rural Water Association (DRWA), located in Milford, Del., is a non-profit trade organization, one of 47 state affiliate members of the National Rural Water Association. The mission of the DRWA is to improve the quality ...

Problem A leading food processing company had a problem. Their need to meet safety and cleanliness levels meant an increase in the use of biocides to satisfy these more restrictive standards. However, their ability to effectively eliminate bacteria came with a reduction in needed bacterial action in their effluent wastewater system. Non-neutralized quats in the wastewater at the ...

New regulations by the European Union require laboratory testing for polyaromatic hydrocarbons (PAHs) when recycling or disposing old tar or asphalt from road planings. Sitelab’s portable UVF-3100D and TD-500D analyzers have similar sensitivity to these types of compounds. The equipment is easy to operate and samples can be tested in the field in less than ...

What is Destructive Testing? As pinpointed by the name, Destructive Testing consists of various methods that break down a material in a controlled manner to determine mechanical properties including strength, toughness and hardness. It is often used in conjunction with non-destructive testing. Destructive Testing — Determines robustness and specifies ...

Nitrate is a naturally occurring substance in the environment and is commonly found in most water sources, it is usually only a cause for concern in areas where water supplies can be affected by farm runs offs and agriculture, its use as a fertiliser can cause increased levels in water supplies The ...

Field tests for the detection of lead in soil are not frequently accepted, since the tests are rather cumbersome or not reliable for screening determinations. Recently, we developed the LEADQuick field test kit for the detection of lead in water with 3 g/L sensitivity. This test is further modifiedto detect lead in soil with a sensitivity 0.03 g. We developed an extraction protocol using ...

Demands from the Industry A growing number of customers demand quieter vehicle cabins, and cabin acoustic comfort has become a major concern for the automotive industry. Optimization of the acoustic insulation performance has, therefore, been given a more prevalent role in the design process. In the aircraft industry, acoustic comfort for customers and the use of new, lighter ...

Liquid cooled engines and rotating equipment use glycol based coolants because of their excellent heat transfer abilities. However, glycol based coolants are not desirable at all in lubrication oil itself – Coolant ingression to the lubricant is a particularly nasty contaminant for the variety of damage it can cause. Glycol coolants break down in the high temperature engine environment, ...

Generally water quality testing is done to monitor the maintenance and operation of drinking water systems. In Yemen CARE uses the DelAgua water testing kit (developed by OXFAM, reproduced by the Robens Centre for Public and Environmental Health, Surrey University) as an awareness tool to improve the understanding of ‘clean and safe water’ in village communities. “We have ...

The pocket colorimeter kit by Hach offers an immunoassay method to measure TPH (Total Petroleum Hydrocarbons) in soil samples – a useful indicator of petrol pollution or contamination in soil. For areas of heavy contamination the range of the test can be extended by dilution during the soil extraction step. ...

ProteinWorks and GlycoWorks kits address more than sample prep challenges One of the most challenging parts of an LC-MS workflow happens before analytical chemists even turn to their instrument: Sample preparation. Get it right, and the analytical run performs as expected. Get it wrong, and the assay has any number of problems, from poor sensitivity to poor reproducibility. The ...

Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

In the aftermath of a natural disaster, particularly earthquakes, infrastructure could be damaged and a safe source of drinking water is often not available. This may be due to damaged pipes or water supplies becoming contaminated. Our colleagues at Oxfamstate; “In the initial phases of an emergency it should be assumed that all water sources are contaminated ...
